COMBINATION-WRENCH.

SPECIFICATION forming part of Letters Patent No. 598,897, dated February15, 1898.

Application filed June 17, 1897. Serial No. 641,092. (No model.)

To all whom, it may concern: yBe it known that I, CASPER BIOKEL, acitizen of the United States, residing at Shelburne Falls, in the countyof Franklin and State of Massachusetts, have invented certain new anduseful Improvements in Combination- Wrenches; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a Wrench which is adapted for use both as anut-wrench and a pipe-wrench or tongs and for various other usefulpurposes.

The object of my invention is to provide a combination-wrench which isvery convenient in use and the operating parts of which are quicklyadjustable and partially automatic,

and which is so constructed as to comprise several different kinds oftools in one.

The parts and combinations of parts constituting my invention will bedefined in the claims.

I will now describe the details of construction of my combination-wrenchby reference to the accompanying drawings, in which- Figure 1 representsa top plan view of the wrench with the cover removed for showing theoperating parts. Fig. 2 represents a top plan View of the cover. Fig. 3represents a transverse section on the line fr an, Fig. 1. Fig. 4represents a transverse section on the line y y, Fig. 1. Fig. 5represents a transverse section as viewed from above on line z z, Fig.1.

The working parts of my wrench are inclosed in a sheet-metal case l,preferably of steel and having aremovable cover 2. Near the opposite endof the case 1 are secured the transverse braces Sand 4, havingscrew-holes, as shown, to which are secured the cover by the screws 5and 6. Holes 7 and 8 are made centrally in the braces 3 and 4 in a linewit-h the central longitudinal axis of the wrench for receiving andsupporting the locking-bars 15 and 19.

At the lower end of the casing are placed the two adjustable jaws 9 and10, passing out through the end opening 12. These jaws are angular, asshown, and the interior shanks or bodies are provided with longitudinalslots 9 and 10, with which there engages the trans- The inner portionsof the jaws are provided upon their adjacent edgeswith serrations 9b and10b., which are inclined forward, as shown, for engaging with similarserrations upon they V-shaped head 16 of the locking-bar 15'. The outerends or gripping portions of the jaws are also serrated, the teethpreferably being inclined in opposite directions in the oppofsite jaws,so as to better serve as a pipewrench, though the serrations may be madewithout being inclined forward or backward in either jaw. .Near thelower end of the casing are secured two sti flat springs 14 14, bearingupon the outer edges of the inner ends of the jaws, so as to throw theminward and hold them in engagement with the serrated head 16 ofthelocking-bar.

The locking-bar 15 passes through the central opening 7 in the brace 3,and at its upper end extends into the socket 22 of the u'pperlocking-bar 19. .A knob or button 17 is screwed by its stem or otherwiseattached to bar 15, and the stem of said button passes through thelongitudinal slot 18 in the cover, as shown in Fig. 2. 4

The upper locking-bar 19 is provided with the interior longitudinalsocket 22 to receive the spiral spring 23 andthe upper end of bar 15 andpasses through a central opening 8 in the brace 4, by which it issupported. The spiral spring 23 bears at its lower end upon the bar 15and at its upper end upon the bar 19 Within the socket, so as to forcethe bars outward toward the opposite ends of the casing for locking thewrench-jaws at each end. A knob or button 20, having a short stem, isscrewed into or otherwise attached to the tubular bar 19, and its sternpasses through the slot 21`in the cover 2. The upper end of bar 19 ismadewith a V-shaped notch 24 for bearing upon the inwardly-bentleverfhandles 28.

The grip -or wrench 26 is provided with suitable jaws 27 for receivingthe shanks of small IOO tools-such as a screw-d-river, gimlet, &c.-which jaws are pivotally connected by a pin 29 to the casing and extendthrough the opening 25 in the end of the casing. The rear extensions ofthevjaws 27 are in the form of angular lever-handles 28, bent inward tofit the V-"shaped notch 24 of the locking-bar 19. Since the locking-bar19 is tubular and the upper end of the bar 15 works in its socket, eachbar acts as a guide for the other one.

In the upper end of the casing I make a tool-pocket 30 by securing alongitudinal partition 31, composed of a steel plate extending betweenthe brace 4 and the top and bottom of the casing to the outer end of thesame. An end cap 32 can be secured in place by a screw-threadedconnection or by springs or in any other desired manner.

To operate the wrench, the jaws 9 10 are spread apart and thelocking-bar 15 pulled up, when the springs 13 will push thejaws outwardto fit any nut. Then the arm 15 is let down, when its serrated end willengage the serrations 9b and 10b on the jaws, and the springs 14 willpush in the jaws, locking the parts together. The bar 15 having beenpulled up by the knob 17, it will, as soon as released, be pushed downby the spiral spring 23. The fiat springs 14 will keep the jaws in placeand act as a guide.

If it is desired to use the device as a pipewrench, the pointed jaw 9should be kept somewhat retracted, as shown in the drawings, andallowing it to remain stationary the jaw 10 is pulled downward andoutward just enough to give the upper one a good hold on the pipe. Thenthe locking-bar 15 is set a-nd caused to engage the serrations on thetwo jaws. The device can now be conveniently used as a pipe-wrench. Itwill thus be seen that the device can bya little adjustment be used bothfor a nut-wrench and a pipe-wrench.

vWhen it is desired to use the grip or wrench 26, the bar 19 is pulleddown by its knob 20 and the shank of a screw-driver, gimlet, or othersmall tool is placed between the jaws 27 and then the bar 19 isreleased, when the spiral spring will push it up against the benthandles 28 and tightly close the jaws. The spiral spring 23 constantlyforces both the lockingbars 15 and 19 outward, so that they always bearupon the jaws at the opposite ends of the casing.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a wrench, the combination with the casing, of twoyieldingly-supported jaws, having serrations upon their back edges and asliding locking-bar having serrations upon two opposite edges or faces,adapted to engage with the serrations upon said jaws, sub-V stantiallyas described.
